ASTM A268 Staalpyp
Hierdie spesifikasie dek 'n aantal grade van nominale-wanddikte, vlekvrye staalbuise vir algemene korrosiebestande en hoë-temperatuur diens.Die meeste van hierdie grade staan algemeen bekend as die "reguit-chroom" tipes en word gekenmerk deur ferromagneties.Twee van hierdie grade, TP410 en UNS S 41500 (Tabel 1), is vatbaar vir verharding deur hittebehandeling, en die hoë-chroom, ferritiese legerings is sensitief vir kerfbrosheid by stadige afkoeling tot gewone temperature.Hierdie kenmerke moet erken word in die gebruik van hierdie materiale.Graad TP439 word hoofsaaklik gebruik vir warmwatertenkdiens en vereis nie na-sweis-hittebehandeling om aanval van die hitte-geaffekteerde sone te voorkom nie.
